Biography
al-Mustakfi was born on 23 March 1285, the son of Caliph al-Hakim I of the Abbasid Caliphate (now without temporal power, based in Cairo, Egypt). He became caliph on 20 January 1302 after the death of his father, and his early reign saw the fall of Ruad, the end of the Crusades; he went on to defend the city of Damascus from the Tatars of the Mongol Empire's Ilkhanate that same year. In 1304, al-Mustakfi invaded Nubia after the Nubians broke their covenant with the Mamelukes of Egypt, and in 1337 he declared a jihad for Castile against Alfonso VII of Castile.
